It’s taken a while for me to discover the simple solution as to why one of my 2 UITouch objects when grabbing the allTouches set from the iPhone SDK touchesMoved event always resulted in 0,0 co-ordinates in my view…
NSSet *allTouches = [event allTouches];
Solution: you need to switch on the multipleTouchEnabled property of the view you want to get multiple touch events from!! ie:
[self.view setMultipleTouchEnabled:YES];
Hope this post helps others…
